INTERLOCKING- TERMINAL BASE.

Specification of Letters Patent;

Patented March 26, 1907.

Application filed n is, 1903. Serial No. 161,993.

. Be it known that 1, Louis STEINBERGER, a citizen of the United States,. and a resident of the city.of New York,.borough of Brook in the county-of Kings and State of York, have invented a new and Im- 'provedlnterlocking Terminal Base, of which the following is-a full, clear,- and exact description. t

invention relates to terminal bases used'in telephony and analogous arts, my more particular object being to produce built-Sup terminal bases of composite charzacters made of separable parts capable of in-.

1- 'electrical connections. I

terlocking and provided Reference is .to behad to the accompanying drawingsyforming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

'Figure 1 is a perspective view showing the .-baseinuse.. Fig. 2 is'a section through one of the base-sections and showing one of the bindin s crews as connectedtherewith, and. 5 screw.

Fig 3 1s a perspective view 'of the binding- A number of base-sections are each'projvi'ded with'a screw-hole 2, throughwhich a screw may be-passed forthe purpose of securing the base-sections upon a suitable sur-- face, if desired'.- Each base-section is provided with a binding-screw3, fitted with nuts 4 5 and washersfi 7. Each binding-post is flattenedat its bottom portion 8 and is embedded in the base-section, v as indicated in EFig; 2, so as to become practically integral therewith. The upper portion 9 of ca "binding-screw is upset for the purpose of pre "ventingthe'removal of the nuts and washers.

Integral each {base-section 1 are pro- I providedwith longitudinal j eads 12 113, separated from the main body' of-insulating material vby grooves14 15'. Y The projections 10111- and beads 12 13 together edges oftwo -adjacent base sections are renconstitute 'hook like members whereby the dered interlocking, "as indicated in- Fig. I.

Thebeads 12-13 of each base-section enga e.

the'grooves 14 '15 of the sections immediate y with, appropriate adjacent: thereby securing the base-sections I together and'making a joint through which surface leakage cannot occurthat is to say, a

the line or plane through which leakage can occur is greatly lengthened. Any number of these base-sections may be connected rigidly and accurately together into a base and any number of bases may be employed. The apertures or screw-holes 2 furnish an auxiliary means whereby the base-sections may be secured in place independently'of the interlocking edges, and each section may, if desired,

be secured position by .the joint action of the-interlocking edges of the screw or other v member passing through the aperture ,2. y

Ido not limit myself to the. particular form of interlocking oints herein shown, as many other forms of interlocking joints will readily occur to the minds of. those skilled in the-art to, whichmy invention appertains; nor do 1 limit Jinyself to the use of. any par-' ticular insulating'materialfor the construction of-the base-sections; but I prefer to use the well-known insulating material designated in the trade as electrose,and having many of the properties of hard rubber.

Having thusdescribed my invention, I

claim as. new and desire to secure by Letters Patent- .As an article of manufacture, an interlocking terminal-base section consisting of abody portion of insulating material provided with .interloclring edges, and metallic binding posts mounted upon said body portion, each of said bindingosts being provided with an enlarged end embedded within said body portion, and further provided with a threaded aperture to be engaged by a screw fo'r holding the same in position.

In testimony whereof I have signed my' name to this specification in the presence of two subscribing witnesses.
